Updating the software
The purpose of this update is to ensure that the E6640A’s software, its measurement
mode applications, and the FPGA content of its PC boards are all current and up to date.
NOTE An update to the instrument software revision does not require a new license key for the
measurement applications, so long as the applications were licensed prior to the update.
NOTE This procedure will only update the instrument software that currently resides on the C:
drive of the instrument. It will not update the version that exists on the recovery
partition. Because of this, if the recovery process is performed, the instrument will
revert back to the instrument software revision that was originally shipped from the
factory.
Determining the current software revision
To determine what revision of instrument software is currently installed, press System,
Show, System using the instrument’s virtual front panel. You can access the virtual
front panel using a mouse and right-clicking in the application window, and selecting
Utility, Virtual Front Panel. Once in the show system screen, look for the "Instrument
S/W Revision" entry (for example: "A.13.85"). If the installed revision is the same as the
latest revision on the web, there is no need to update the instrument software.
Requirements
The following requirements must be met to use this procedure:
• The E6640A must be functioning properly before the update is attempted.
• You must have a USB keyboard and mouse.
• You must be able to log in to the instrument as the administrator.
• You must be able to transfer a large file (~1 GByte) to the E6640A being updated.
File Download
1. Go to http://www.agilent.com/find/e6640a and go to the Technical Support section;
select the Driver, Firmware & Software tab.
2. Download the executable file by clicking on the file link. Save the file to a location of
your choice. If you do not have the ability to download files directly to the C: drive of
the E6640A being updated, store the file on a large capacity USB storage device for
transfer to the instrument. (The file size is ~1 GByte.)
